The OnkoAktiv network is coordinated by the NCT Heidelberg, conceptionally developed in close cooperation with the "Krebsverband Baden-Württemberg e. V." (cancer association Baden-Württemberg e. V.) and supported by the "Sportregion Rhein-Neckar". OnkoAktiv sees itself as an integrating network and does not aspire to reinvent existing programs or structures.
The cooperating institutions of the network, however, observe defined quality standards which promote appropriate professional treatment and care. Those eligible to join include rehabilitation institutions, commercial health providers (fitness studios offering therapeutic sports programs and sports and physiotherapy practices), sports clubs and associations with oncologic programs and corresponding qualifications, as well as oncologic centers/institutions, established oncologic practices, and any other supporters. All those taking part in OnkoAktiv see themselves as pioneers in the network-oriented physical therapy work with oncologic patients. In addition, there are three OnkoAktiv Centers, which independently recruit further training and therapy institutions. These are the Hospital of Coburg (since 2017), the Northwest Hospital Frankfurt (since 2017) and the Hospital of Hamburg-Eppendorf (since 2019).
